No matter how I work it out, the samples are cheaper by about US$4. So, not that much. However, I've read a review that said what was in the samples was miles better than the full size product. Every other review I can find raving about the product have only reviewed the samples -gargh-.

I don't mind spending a few extra dollars for the convenience of a full product, but I don't want to buy something that I won't enjoy as much as the samples.

Has anyone used both and can offer their experience?

My skin is really enjoying this cleanser and I can see it's responding well. But the down side is I only have about six samples left (wah), so I'd rather make the purchase sooner than later.
